How does your stomach tell your brain its hungry?
iVinArrow [24]
<span>There are two hormones that determine whether you fell hungry or full -- ghrelin and leptin. Ghrelin sounds like gremlin, and it's the hormone that makes your stomach churn and says, 'Hey, you gotta eat.' The second, leptin, sends message from fat that tells your brain you are full.</span>

A scientist wants to begin making a DNA fingerprint, but she has only a very small DNA sample. What should her next step be
azamat

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.

Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-

1. Denaturation of the double-stranded DNA (at around 95°C)

2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)

3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).

With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

Which of the following statements best supports the claim that organisms share fundamental processes as a result of evolution? (
podryga [215]

Answer:

C

Explanation:

All living organisms' cell are composed of genetic material in form of DNA. The DNA encodes the information needed for the production of useful products (proteins). The way in which the information is encoded is called the GENETIC CODE. It consists of all the triplet nucleotides in DNA or RNA that encodes an amino acid.

This genetic code is universal i.e. the same genetic code is employed by virtually all living organisms, as a codon does not encode another amino acid in another organism. It is universal that AUG specifies Methionine in all living organisms. This shows that all organism share a common evolutionary history.

Hence, it is possible for an organism to express a gene from another organism since the same genetic code will be used to read the information in the gene.
